So my wrong (Altcoin) selection lead me to break my dreams. If I were just left Bitcoin rather than move into altcoin then I should be in a good position today. Now 1.5 BTC is worth too much especially when it was above $60K.
Maybe not all altcoins can give you such regret. If you shifted into binance or Ethereum, I think it may not affect you as you complain now. Binance in 2018 was still extremely cheap while Ethereum was still below hundred, you can see the difference in price now and you got big money for investment too which can help to put more profit to your wallet. You actually made a mistake and a lesson to learn.
